What Is Smallpox?

Smallpox
is a disease caused by a virus. At one time, it was one of the world’s most feared infections. Smallpox has no treatment or cure. It can be fatal. Smallpox is nearly nonexistent as a result of a worldwide vaccination effort. The last case in the US was in 1949. The last naturally occurring case in the world occurred in 1977. There have been no cases of smallpox reported anywhere. The vaccine is no longer given.

Because of bioterrorism threats, it’s important to remember the facts about smallpox.

Smallpox can be spread from person to person by direct, face-to-face contact. It can also be spread through bodily fluids or linens and clothing that have been contaminated. Smallpox can be spread through the air, although this is rare.

The primary symptoms include:

High fever

Headache

Body aches

Vomiting

As the virus advances, a red rash appears on the tongue and in the mouth. The rash then spreads. Spots begin to break open. The rash spreads across the body. It turns from red spots into raised bumps. By day 4, the bumps fill with fluid and have a depression in the middle. Scabs form over all of the bumps.

What Is the Smallpox Vaccine?

The smallpox vaccine contains a live virus, called the vaccinia virus. This is related to smallpox. The vaccine is given as multiple pinpricks usually in the arm.

Who Should Get Vaccinated and When?

You should get the vaccine if you have come in contact with the virus or if you are at risk. The vaccine is not given to the general public. You will get the vaccine if you are in the military and work in high threat areas.

What Are the Risks Associated With the Smallpox Vaccine?

A live virus is injected into the skin. It is possible to spread it to other areas of the body, or even to other people. The injection site must be protected to prevent this from happening.

Common side effects of smallpox vaccine include:

Rash and itching

Fever

Headache

Tiredness

Swollen lymph nodes

Body aches

Soreness in the arm

More serious, but less common side effects include:

Inflammation of the heart muscle or sac around the heart

Swelling of the brain or spinal cord

Infection at the site of the vaccine

Severe allergic reaction

Who Should Not Get Vaccinated?

The following people should not get vaccinated:

People who have had a previous allergic reaction to the vaccine or any of its components

Pregnant or breastfeeding women

Children less than 12 months old

People with
eczema
or who have had a history of eczema or other skin conditions, such as
atopic dermatitis

People with weakened immune systems (such as those who have received a transplant, have
HIV
, are receiving
cancer
treatment, or are taking medicines that suppress the immune system, including steroids)

Talk to your doctor to find out if the vaccine is safe for you.

What Happens in the Event of an Outbreak?

If an outbreak happens, the US has a large supply of the smallpox vaccine to vaccinate the entire population.
